So I decided to measure to frequency response in my room. I am using a calibration mic with spectrum analyzer software (TrueRTA). As sound sources I used Audacity to create multi-channel PCM files with pink noise. I first used Audyssey to calibrate and then made my own tweaks.

My first question, am I correct to use pink noise over white noise?

In a typical room, what kind of spread would I expect to get after calibration? I seem to be getting +-5 db more or less from about 25Hz to 15KHz. Is this good, bad?

When measuring/adjusting frequency response, I am focused on the Front, Center and LFE. I approached this task by trying to adjust Front, Center and LFE individually and then combined. Is this a good approach?

It's funny, I have never tried measuring room response like this before, I always assumed it was pretty straight forward to do. Ha, once I started to plan for it, I discovered that there are tons of details to think about.

Yes, in fact I discovered it is. You can set it to Manual and then it makes available a 5 channel equalizer that you can apply to different speakers. It also allows you to "copy" the equalization curves it set as a starting point. In addition I get an old fashioned tone control for bass and treble.

I like Audyssey but I find for movies there isn't enough of a high frequency roll off. And in playing around with the settings trying to find a way to lower the high end I discovered the manual stuff.

I am now able to start at the point Audyssey sets and then make my "tweaks". I need to do more experimenting but after my adjustments today, I think it is going to work out well.

Finally, manual adjustments are nice but I lose Dynamic EQ and Volume. I don't use Dynamic volume but I do/did use EQ. I guess I will know soon enough if I will miss it.

No, that's incorrect. There's a choice as to whether to use the Audyssey adjustments or to turn Audyssey off and attempt a manual equalization, but the manual settings can't be applied to the Audyssey results. Dr. Kyriakakis has commented several times on this, for example here, and has emphasized that manual settings aren't possible while retaining the Audyssey equalization results. Again, there's a choice, but Audyssey can't be tweaked.
